摘要

银鞍鱼分布在印度-西太平洋沿岸：从波斯湾到印度尼西亚、日本、韩国西部和西南部以及中国东部，并在所有这些国家形成了商业渔业。为了制定银鱼的渔业管理策略，准确的种群信息是必要的。利用12个多态性微卫星标记对北印度洋银鱼的遗传种群结构进行了研究。形态和分子研究证实，北印度洋沿岸的银鞍子是潘普斯。使用微卫星数据，阿拉伯海和孟加拉湾地区（FST=0.049，P<；0.05）的念珠菌种群显示出显著的遗传分化，多位点距离矩阵检验（主坐标分析）和基于模型的聚类进一步支持了这一点。研究结果表明，在研究区内有三个不同的银鱼遗传种群。

Spatial structuring of silver pomfret Pampus candidus in Northern Indian Ocean using microsatellite DNA

Silver pomfrets are spread along the Indo-West Pacific: from the Persian Gulf to Indonesia, Japan, West and Southwest of Korea and Eastern parts of China and forms a commercial fishery in all these countries. For formulating fishery management strategy of the silver pomfret, accurate population information is necessary. The genetic stock structure of silver pomfret in the Northern Indian Ocean was explored using 12 polymorphic microsatellite markers. Morphological and molecular studies confirmed that the silver pomfrets along the Northern Indian Ocean is Pampus candidus. Pampus candidus populations along Arabian Sea and Bay of Bengal region (F_ST = 0.049, P < 0.05) using microsatellite data revealed significant genetic differentiation which was further supported by multi-locus distance matrix testing (Principal Co-ordinate Analysis) and model-based clustering. The results indicate that there are three distinct genetic stocks of silver pomfret within the study area.

期刊介绍： Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
